I had a Littman Classin II. I liked it. I recently bought the Littman Master Cardiology.
I could hear on the Classic but I can hear a lot better on the Master and I didn't want to risk not hearing something during an assessment class.
I had my name laser engraved on my Master because it was expensive. I tend to forget it but so far my fellow students have been really good at grabbing it for me. I tend to take it off for baths and isolation rooms and that's when I forget it and leave it behind. I don't regret the Master at all...I'm so glad I got it.
I can recommend
www.reddingmedical.com for purchases. I ordered my Master with laser engraving at 2:00 one afternoon and I kid you not...it showed up the next day at about 2:00. I did not do the expedited shipping. Amazing service...blew me away.
I have heard some people say go cheap. For me it's not worth it because next we do heart sounds and more in depth breath sounds and while my hearing is fine...it's not the best and I'm not risking my schooling for something like this.
